In the biggest sign so far that this is now Marissa Mayer's Yahoo, the Web company began rolling out a major redesign Wednesday morning to U.S. users.

Yahoo.com users will be greeted by a new news-feed feature that allows them to scroll down continually for more news articles that have been gathered based off their interests and preferences. Users can also log into Yahoo using their Facebook account to gain a more personal experience.

Besides the news feed, Yahoo also said it has newly designed homepage applications. That includes applications for stock quotes, sports scores and Flickr photos.

"Yahoo! has always been about bringing you the very best of the Web. And today, we’re introducing a new, more modern experience to do just that," the company said in a statement.

One of the biggest changes with the site, however, isn't visible. The company said it has made "under the hood" improvements to make Yahoo.com faster. Additionally, the experience between Yahoo on a computer, phone and tablet are now more uniform.

The redesign is the latest effort by Mayer, a former Google executive who took over Yahoo's helm last summer, to resuscitate the struggling Internet company.

U.S. users will begin to see the changes to the site over the next few days.
